Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.

小肠活检表现为上皮下胶原沉积，绒毛萎缩程度不一，上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检，表现为其他肠病改变，并没有胶原沉积。7例患者合并胶原性结肠炎，且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻（CD，谷蛋白敏感性肠病）病史。5例患者经无麸质饮食和免疫抑制治疗后，临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排，其中5例发现有克隆性T细胞群，这5例中有4例治疗后临床症状加重，且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻；其余患者无CD病史，他们的发病也许是生物源性损害，而非谷蛋白敏感。

Under light microscope, on H-E stain section, four types cells can be distinguish: cells with weak basophilic fibrillar elements; cells with acidophilic granular substance; cells with strong basophilic fibrillar elements and ciliated cells. In the basal lamina region under gland epithelium, there are a few connective tissue; Surface view of the hypobranchial gland could be see by scanning electron microscope, there are cilia and different kinds of secretions distributed. Ultrastructure of the hypobranchial gland could be understand by transmission electron microscope, supporting cells, sensory cells and seven types gland cell were observed to form the glandular epithelium; cells with much rough endoplasmic reticulum,smooth muscle fiber and nerve endings were found beneath glandular epithelium, among basal lamina region.

光镜下H-E染色切片中腺上皮区仅可以区分出四种类型的细胞：弱嗜碱性纤维样细胞、强嗜碱性纤维样细胞、嗜酸性颗粒分泌细胞和纤毛细胞等；腺上皮下的基底膜区有少量结缔组织存在；扫描电镜下可以观察到鳃下腺表面的纤毛及腺细胞的分泌物等情况；透射电镜下观察到腺上皮中有支持细胞、感觉细胞和7种类型的腺细胞；近基底膜区观察到富含粗面内质网的细胞；基底膜间为薄层疏松结缔组织，内含肌细胞及神经末梢等结构。

RESULTS: Slitlamp microscopy examination: After bothsided LASIK, the cornea central region was transparency and had no haze. At early stage, epithelium thickened at the edge of the flaps and corneal stroma was slightly irregular, which tended to normal with the time.
